When applying TENS, which safety consideration is essential?

• A. Always set the device to maximum intensity for effectiveness
• B. Place electrodes directly over the heart
• C. Avoid skin burns; ensure safety near pacemakers or defibrillators and adjust intensity appropriately
• D. Ignore skin checks during treatment

Answer: (C)

Safety with TENS hinges on preventing skin injury and avoiding interference with implanted cardiac devices, while using the lowest intensity that achieves the desired sensation. The most essential step is to prevent skin burns by ensuring good electrode contact, using appropriate gel or conductive material, checking the skin before and after treatment for redness or irritation, and starting at a low intensity and increasing gradually to a comfortable sensory level rather than attempting to achieve a strong or painful response. At the same time, be mindful of any implanted devices such as pacemakers or defibrillators; avoid or seek explicit medical guidance for stimulation near the chest or around these devices because external electrical currents can affect device function. By combining careful electrode placement, skin monitoring, and appropriate intensity adjustments, you maximize safety and comfort during TENS.
